First radar images of asteroid 1998 QE2 were obtained when the asteroid was about 3.75 million miles (6 million kilometers) from Earth. (NASA/JPL-Caltech/GSSR)
On May 31, 2013, asteroid 1998 QE2 will sail serenely past Earth, getting no closer than about 3.6 million miles, or about 15 times the distance between Earth and the moon. (NASA/JPL-Caltech)

The Herschel Space Observatory captured asteroid Apophis in its field of view during its recent approach to Earth, Jan. 5-6, 2013. This image shows the asteroid in Herschel's three wavelengths: 70, 100 and 160 microns. (ESA/Herschel/PACS/MACH-11/MPE/B.Altieri (ESAC) and C. Kiss (Konkoly Observatory))
At about 36 hours from the minimum distance (9.3 million miles or 15 million kilometers from Earth), potentially hazardous asteroid Apophis was imaged again with the Virtual Telescope, on Jan. 8, 2013. (G. Masi & F. Nocentini)
